Aqueous-phase catalyzed reduction of organic contaminants via zerovalent copper nanoparticles (nCu), coupled with borohydride (hydrogen donor), has shown promising results. So far, the research on nCu as a remedial treatment has focused mainly on contaminant removal efficiencies and degradation mechanisms. Our study has examined the effects of Cu/Cu ratio, surface poisoning (presence of chloride, sulfides, humic acid (HA)), and regeneration of Cu sites on catalytic dechlorination of aqueous-phase 1,2-dichloroethane (1,2-DCA) via nCu-borohydride.

PFAS have surface active properties that have made them suitable for applications in oil- and water-resistant products, as well as many firefighting foams. No on-site remediation strategies exist to treat PFAS impacted soils.
